METALLIC PACKING-RING.

Application filed November 18, 1913.

To all whom it may concern:

Be it known that I, CHARLES EDWARD LUCKE, a citizen of the United Statesof America, residing in the city, county, and State of New York haveinvented certain new and useful Improvements in Metallic Packing-Rings,of which the following is a true and exact description, reference beinghad to the accompanying drawings, which form a part thereof.

My invention relates to metallic packing rings, such as are used inpacking piston rods and the like, and particularly to that type ofmetallic packing rings which are divided into two segments or sectionsby substantially parallel cuts substantially tangential to the innersurface of the ring.

The object of my invention is to so construct the ring segments thatthey will, when assembled upon a rod, interlock with each other and therod in such a manner as to prevent the lateral movement of eithersection away from the rod to such an extent as would result in thedisengagement of the ring sections from each other.

My invention will be best understood as described in connection with thedrawings in which it is illustrated, and in which Figure 1 is a planview of a packing ring constructed in accordance with my invention. Fig.2 a side elevation of the said ring. Fig. 3 a similar side elevation ofa ring having a tapered end but otherwise similar to the ring of Fig.52, and Fig. 4 aperspective view showing the mode in which the ringsections are assembled on a piston rod.

A and A indicate the ring sections and when assembled together make up acomplete ring divided by parallel tangential cuts D D into the twosegments. This division of the ring leaves each segment with a taperedoverlapping end B and a tapered underlapping end C, and under theexigencies of use the ring, as it wears, can maintain close contact withthe rod by the movement of the two sections toward each other in linesparallel to the lines D D. B is a projecting lug or finger as shownandpreferably formed on the end-of the overlapping end B and extendingdown into a notch C formed preferably in the outer end of the taperedend C of the other ring segment. By preference both ends of the ringseg- Specification of Letters Patent.

ments are made with the fingers or lugs B and notches C as shown.

It will be obvious that the ring sections constructed in accordance withmy invent1on can be readily placed upon the rod by moving them laterallyagainst it and then can be made to interengage with each other by movingthe sections parallel to the rod until their ends overlap and engage. Itis also obvious that when so engaged the rod and ring sections are sointerlocked that neither section can be moved away from the rod whenfirst disengaging it from its corresponding section by a longitudinalmovement.

I am aware that sectional interlocking rings have been made inaccordance with the structure described and shown in the King Patent No.914,426, but the King rings are intended to operate in a somewhatdifferent manner than the rings separated by parallel tangential cuts towhich my invention relates and to which type of ring it is my inventionto impart an interlocking feature which they have not hithertopossessed.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is,

1. A metallic packing ring made of two segments separated by paralleltangential cuts and having tapered ends overlapping along said cuts, oneof said tapered ends having a projection and one corresponding endhaving a registering groove to receive said projection whereby saidsegments are locked against lateral displacement from a rod whenassembled upon it.

2. A. metallic packing ring made of two segments separated by paralleltangential cuts and having tapered ends overlapping along said cuts, oneouter tapered end having a projection at or near its outer end and thecorresponding inner tapered end having a registering groove formed atits outer end to receive said projections whereby said segments arelocked against lateral displacement from a rod when assembled upon it.
